The condition occurs due to an electrical problem with the heart. This can occur because of certain medical conditions or the use of some medications. Using caffeine, nicotine, alcohol or other drugs can increase the risk.
What are the symptoms of supraventricular tachycardia?
When supraventricular tachycardia occurs, the rapid and irregular heartbeat can lead to heart palpitations, as well as shortness of breath, anxiety and chest pain. Dizziness or loss of consciousness can also occur.
What are supraventricular tachycardia care options?
Some lifestyle changes like avoiding smoking, alcohol and caffeine can help reduce the incidence of supraventricular tachycardia. In some cases, emergency treatment may be needed to slow the heart. Certain catheterization procedures, called ablations, can treat the heart and reduce the chances of supraventricular tachycardia occurring.
